Can Sexual Activity before a PSA Test Elevate PSA Level?

Health Professional

Dear Dr. Motola,

Can sexual activity just before a PSA blood test make PSA results jump from 2 to 12?

PSA testing immediately after sexual activity remains controversial.   The most widely held belief is that patients should wait 3 days after sexual activity prior to obtaining a PSA, however some recent studies suggest that sexual activity will not cause a rise.   Repeating the PSA after 3 days of abstinence will be the easiest way to resolve this.
